J OB SHERIDN TINDALL, OF PUEBLO, COLQRADOQ- EXCAVATING AND LOADING MECHANISM.

Sbecication of Letters *Patent Patented Sept. 17, 1912. Application `iled August 2, 1910. Serial No. 575,146.

Be it known t-hat I, lJois SHERmAN TIN- D'ALL, a citizen of the United States, and a resident of Pueblo, inI the county of Pueblo and' State of Colorado, have invented a certain new and useful Improvement in Excavating and LoadingMechanism, ofI which the following Ais a full, clear, and exactV description.v

My invention is an improved excavating and Wagon \loading machine. y

The object of my invention is to provide a simple and eflicient device .which may be elevation of the mechanism shown 'in Fig.A

1; Fig.-3 is a plan of the device, showing it in inoperative position; Fig. 4 is a face and side view ofthe boxing on which theframe of the mechanism is mounted; Fig. 5 is a face view and cross-section of an end of the cbannelirons of which the frame is formed; and Fig. 6"'is a side view of a bucket and a portion of the chain, showing the manner of mount-ing the buckets.'

In the drawings 1 indicates the body lof the wagon which is mounted on Wheels 3, 3.-

Secured to the inner part f thefhubs. 'of

the rear Wheels are gears 4 meshing with gears loosely mounted on the counter-#shaft 27. .The shaft27 is journaled in brackets 28 bolted itothe rear axle 29. The'gears 5 have a dented inner shoulder 5 which is in position to engage a correspondingly dented'face on a clutch member 25 which .clutch member is splined-on' the shaft 27 and forced toward' engagement with the shoulder 5a by a .coiledspring 26. On the members 25 there is a cam ring 25, the pur- Y pose of which will later appear.1

The excavating or loading mechanism proper is carried byfa frame built up of channel irons. This frame has lower' del pending members 10,*vertical members 10a and upper depending members 10b. Crossed braces 11, 12 hold the members 10, 10* and vlflalvvays in the same angular relation.

The frame is pivotally connected to the counter-shaft 27 by means of a boxing 2O (shown in Figs. 4 and 5) which also forms a means of rigidly jattaching the' channel irons 10 and 11 by bolts or rivets passing through'the holesI 30, 30 in the boxing and 31, 31 in the channels. The shaft 27 fits easily in the opening 32 in the hub of the boxing. Boxings 20 also serve to connect the channels 10 and 10a, 10a and 10b, and to journal the shafts 33 and 34. -A similar y boxing -20a with three arms, join thechannels 1()b and 12 and forms a mounting for the strut 36 and the shaft 35. `The strut 36' is divided intermediate its lengt-h to receive boxing .for the shaft 37. I

YMounted on the counter-shaft 27' are Aa pair of sprocketsa and a corresponding pair of sprockets 6b are mounted on the shaftl 33. `Driving chains 7 onthe sprockets 6a and 6l transmit power from the shaft 27 to the shaft 33.

The excavating mechanism comprisesV 37 ,'6, on shaft 35, and 6d on shaft 34. l/Vhenv the buckets -passover sprocket 21 they are inverted and dumped, the material exea vated being guided by the open front hop per 13 onto the endlesstraveling belt 14 which delivers it into the Wagon. The belt` 14 travels over the pulleys 22 mounted in a frame 15.l The side members, of4 the frame are supported at the rear on a shaft 15a by a link 2 pivoted to the bottom of the `Wagon bed.` The belt 14 is driven by a belt lo' passing over the pulley 17 on the shaft -journaled in the braces 12 and at the front Q igosaeea 15a whichbelt 1G is actuated from the pulley 18 on the shaft 37.

The excavating mechanism is shown in Fig; 1 lowered int-o operative' position. When the wagon is filled, orv for any other reason it is desired to stop the excavating mechanism, it is swung about the shaft 27 as a center. This is accomplished by winding the chain 40, connected with the frame by the rod 19, around a shaft upon which the ratchet lever-41 is mounted. This Vshaft is prevented from turning inthe reverse di rection by a dog '42 contacting with the ratchet wheel 43.and the lever 41 ispro'- vided with a `ratchet also to engage the ratchet wheel 43 for turning the shaft and winding up the chain. Through these means the frame may be raised through the dotted arcs' A into the vdotted line position B, in

which its lowest part will easily clear-fthevv ground.

I have provided'mechanisin for throwing the counterwshaft- 27 out of gear whenthe yexcavator is in inoperative position, which said cams draws the members 25 away from and out `of Contact with the dentatedshoul? ders of the gears -thus stopping the rotation of4 the'clutch members 25 and thel shaft 27 on which said members 25 are splined. When the frame is again lowered .and driven by said second counterfshaft," 55

into operative position the arms .24 pass out of contact with the cams 25"L and the springs 26 return the members 251:0 contact with theshoulders on the gear 5. 'l

.Having thus described my invention, what Iclaim is: 1. In an excavatingmachine, the combination with a driven counterfshaft, of a frame pivotally mounted thereon, sprockets mounted on said counter-shaft, a second countershaft journaled yin said frame, driving chains carried on said sprockets and transmitting motion to said second counter-shaft, an endless conveyer chain carrying 'buckets idler sprockets mounted in said framesaid -conveyer .Chains passing up oversaih4 idler sprockets and inverting said buckets "at the upper part of said frame, a 'hopper -below .the place-where the buckets are inverted and an endless'traveling belt below said'hopper in position to deliver material dropped vby the buckets through said hopper. 4"

. 2. In combination, a wagon, gears mounted on the hubs of the Ywheels of said wagon, a countershaft journaled in the bearings on said wagon, gear-wheels freely mounted on' said counter-shaft in position to engage the gears on said hubs, clutches holding said gear-wheels to the tcounterQ-shaft, cams on said clutches, means forengaging said cams ets mounted on said counter-shaft, a second counter-shaft journaled in said frame, driv y ing chains carried on said sprockets fand transmitting motion to said Vsecond countershaft, an endless conveyer chain carrying 'buckets and driven by said second counter-- Y shaft, idler sprockets mounted in said frame,`
